Not so. All sensory input triggers neural activity. It's irrelevant whether or not that input equates to a desire; neural activity still occurs. Whether or not that we attend to that input depends on either top-down or bottom-up attentional processes, the former being the result of conscious processes (e.g., watching the car weaving across the lane in front of yours), and the latter unconcious (e.g., the horn of the car which almost hit you because both you and the car in front of you just ran a red light).

So it's not accurate to say "neuron patterns" only result from desire, though they can.

When these patterns are excited. Also, the sound labels are also excited (which we call words) and are connected to the voice muscle system.
You're focussing exclusively on verbal thought. There's a lot of mental activity which in non-verbal, not to mention unconscious.

Also, it's misleading to say the inner voice "reads these neuron patterns". The "inner voice" is the result of particular patterns of neural activity (specifically in the language and auditory processing areas of the brain in the temporal lobe).

As mind is part of it - Can part of something understood the whole?
As cadmar mentioned, consciousness can be described in relation to activity within the brain. In that regard consciousness could be fully understood because consciousness is part of the mind, not vice-versa.

Of course if you define consciousness as being more than neural activity, then perhaps not, though no one has yet been able to identify consciousness either as neural activity or as something immaterial. So the real answer is: maybe.

That's big "if"!
